For many junior high school students, math difficult, but they have to learn. In the eyes of students, mathematics is a concept, formula, theorem, accumulation of exercises, it is so abstract, scattered, distant, unpredictable, appear cold and blunt. Especially for the understanding and grasping of math concept, it is often imperceptible or touching. The concept of mathematics is the basis of the entire structure of mathematical knowledge.
